See The Effects Of Food And Exercise On Body Weight In Intervals As Short As 15 Minutes.

A weight loss and exercise calculator that handles food, running, cycling, alcohol, and understands glycogen, ketosis and recovery.
A while ago I was on a cycling forum and there was a thread on how much weight you would lose cycling various distances and how much difference would a Mars bar and a can of coke make?

Surprisingly I couldn't find a calculator that would give a detailed answer, so I created this one and having spent a lot of time on it I now understand why I couldn't find one.

This calculator is different to all the others that I have seen because it tries to simulate the effect of food and exercise and weight change is a side-effect of this calculation.

This calculator was never intended to work with a mobile phone.


Personally I find that this calculator has too many questions and a too big an answer to work well on lower screen resolutions. I would suggest that if you are going to spend time using it a tablet, laptop or pc would give a better experience.

I have tried it on an iPhone 5, probably the smallest screen in common use and it works, just about.
